cdefs.h@ 61742

Last change on this file since 61742 was 60964, checked in by vboxsync, 9 years ago
iprt/cdefs.h: Added RT_CLANG_PREREQ macros. Added RT_NOREF_PV macro that uses _Pragma("unused(xxx)") instead of (void)(var), just in case we'll need it.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

1509	/** @def RT_LIKELY
1510	* Give the compiler a hint that an expression is very likely to hold true.
1511	*
1512	* Some compilers support explicit branch prediction so that the CPU backend
1513	* can hint the processor and also so that code blocks can be reordered such
1514	* that the predicted path sees a more linear flow, thus improving cache
1515	* behaviour, etc.
1516	*
1517	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1518	* this compiler feature when present.
1519	*
1520	* A few notes about the usage:
1521	*
1522	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1523	*
1524	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1525	* have some _strong_ reason to do otherwise, in which case document it),
1526	* and/or RT_LIKELY() with success condition checks, assuming you want
1527	* to optimize for the success path.
1528	*
1529	* - Other than that, if you don't know the likelihood of a test succeeding
1530	* from empirical or other 'hard' evidence, don't make predictions unless
1531	* you happen to be a Dirk Gently character.
1532	*
1533	* - These macros are meant to be used in places that get executed a lot. It
1534	* is wasteful to make predictions in code that is executed rarely (e.g.
1535	* at subsystem initialization time) as the basic block reordering that this
1536	* affects can often generate larger code.
1537	*
1538	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1539	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1540	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1541	*
1542	*
1543	* @returns the boolean result of the expression.
1544	* @param expr The expression that's very likely to be true.
1545	* @see RT_UNLIKELY
